PSU-MX2-UL, new in box. Behringer was one of the few that supplied these power adapters, but many other products and companies used this adapter (and did not have replacements) so available inventory was also sold to assist other products when companies could not. At this point the only option we can offer is to wire the supply directly into a mixer. So we would have to have the mixer here. If you want to go that route Please contact me directly at 617-926-8020
